Part of an annual tradition dating back to 1991, this year’s MusiCares Person of the Year concert will be held in Los Angeles, with tickets ranging from $1,500 to $100,000. It sounds awfully pricey, even with that lineup, but it’s for a good cause: MusiCares offers a safety net for musicians who need assistance in times of financial, personal, or medical crisis.

In addition to Coldplay, Perry, and Keys, this year’s list of performers includes Foo Fighters, Alison Krauss, Norah Jones, and past Person of the Year honorees James Taylor and Tony Bennett — as well as McCartney himself, who’ll be promoting his latest album, the collection of pop standards ‘Kisses on the Bottom.’
